Special considerations for biologic medications in pediatric ulcerative colitis.

: More extensive disease, high rates of corticosteroid refractory and dependent disease, and the potential impact of disease on growth and development differentiate inflammatory bowel disease in children from adults. This is particularly evident in ulcerative colitis where pancolitis predominates, success of mesalamine alone in achieving remission is less than 50%, and there is a high need for immunomodulator or biologic therapies.: This review describes the use of infliximab, adalimumab, golimumab, and vedolizumab in the treatment of children with ulcerative colitis but is limited in scope due to the paucity of controlled clinical trials. A search of existing literature with keywords of these specific biological therapies as well as 'pediatric', 'ulcerative colitis,' and 'inflammatory bowel disease' was used to complete this review.: Therapeutic drug monitoring has become standard of care when assessing dosing and changes in therapy and will play a role in future treatment planning.
